SWEEP-PLOW.

SPECIFICATION forming part of Letters Patent No. 475,461, dated May 24,1892.

Application filed September 22, 1891. Serial No. 406,509. (No model.)

To aZZ whom it may concern.-

Be it known that I, AMANUEL M. MILLER, a citizen of the United States,residing at Fairfield, in the county of Freestone and State of Texas,have invented a new and useful Sweep- Plow, of which the following is aspecification.

This invention relates to improvements in sweep-plows; and the objectsin view are to provide a sweep-plow especially adapted for thecultivation of cotton and to so construct the same that the blades orwings thereof may be adjusted for the purpose of plowing between rows ofvarious widths.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of a sweepconstructed in accordance with my invention. Fig. 2 is a rear elevation.Fig. 3 is a detail in perspective of the plow point or shear.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The sweep is curved in cross-section until substantially U-shaped, andtherefore comprises the central shovel-seat portion 1 and the oppositeside extensions 2. The central shovel-seat portion 1 is provided with anoblong slot 3 for the reception of a pair of bolts, through the mediumof which the sweep may be adjusted upon the foot of plow. The upperedges of the side extensions are provided with curved slots 4, andconcentric with the same the lower ends of said extensions areperforated, as at 5.

6 designates a wing, of which there are a pair, one for each of theextensions 2. These wings are curved transversely or concave upon theirouter faces and are adj ustably connected to the extensions by pairs ofbolts '7. By loosening the lower bolt of the pair and the upper boltthereof the latter may move through the slot 4 any desired distance, anda retightening of the bolts will lock the wing in position.

It will be seen that the sweep is capable of being used for cultivatingbetween rows of varying widths, and also I am enabled to replace thewings when worn by new ones. It will be understood,of course, that byraising the wings. the sweep is made narrower and by lowering the samewider.

Having described my invention, what I claim is- The combination,with thesweep curved in cross-section to form the central shovel-receiving seat,which is slotted opposite the rearwardly-disposed triangular sides orflanges, which latter are perforated near their lower ends and providedat their upper ends with curved slots, with which the perforations areconcentric, of a pair of opposite rearwardlydisposed diverging wings andpivoting-bolts passed through the perforations of the wings and flangesand adjusting-bolts passed through the slots of the wings and flanges,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

AMANUEL M. MILLER.
